“…The value of the risk of biological instability of water in the water supply network describes the so-called risk function f(r), defined as the expected value of losses under certain system operating conditions that influence the system's vulnerability (resistance) to threat [3,[26][27][28][29][30].…”

The subject of the work is the analysis and assessment of the risk of biological instability of water. The lack of water stability causes the increased susceptibility of the distribution system to secondary microbial contamination of water and constitutes a hazard for consumers’ health. The risk is expressed as the loss of water supply safety and distinguishes a failure of not meeting certain water quality parameters that can influence physico-chemical parameters and the bacteriological quality of the water supplied to the consumers. In the paper the method of analysing and evaluating the risk of loss of biostability of tap water is presented. The presented analysis was performed on the basis of the operating data from the water treatment plant.

“…The risk matrix is shown in Table 5. Based on the presented risk matrix, a three step scale of risk was proposed:  tolerable risk [1][2][3][4][5][6][7][8],  controlled risk (8)(9)(10)(11)(12),  unacceptable risk [18][19][20][21][22][23][24][25][26][27].…”

“…Access to safe drinking water is essential to health, a basic human right, and a component of effective policy for health protection [1]. Water consumers are exposed to risk associated with the operation of the water distribution subsystem (WDS) [2][3][4][5][6]. The consequence of failure in water pipe network can be a break in water supply for a specified number of consumers or a drop of pressure in water pipe network below the required value [7], resulting in a lack or reduction of water supply to consumers, especially for those who live on higher floors of buildings.…”

The method of identifying areas of risk of failure in water pipe network has been presented including presentation and analysis of risk factors for failure in water main pipe network, the proposal of the method for identifying risk areas using a simulation model of the water distribution subsystems (WDS) operation, and an example of application. In the hydraulic model, the failures of main water pipes as well as the operation of the WDS in the case of contamination were simulated. The proposed method consists of preparing the so-called risk maps and the designation of areas in which the limit values for the identified risk, the first type and the second type according to the assumed risk categories (tolerated, controlled and unacceptable) were exceeded.

“…Ensuring high water quality intended for consumption is one of the main tasks for waterworks. Low water quality causes a number of threats to human health [1][2][3][4]. To ensure the water stability in the distribution system, a disinfection process is used.…”

Water quality is the most important parameter related to water intended for human consumption. The main task of water supply companies is to keep water quality at the possible highest level. Water, which consumers receive in their homes, is the final product of a multi-stage processing, which aims to obtain water with the required physico-chemical and biological composition. Nevertheless, during transport through the Water Supply System (WSS), water reacts with various factors, sometimes causing secondary pollution. An important threat associated with water quality reduction is disinfection by-products (DBP), formed during the oxidation of organic compounds and some inorganic compounds found in water. DBPs has carcinogenic properties, that’s why they are threats for human health.The article presents the results of water quality analysis and risk assessments. In research the real WSS, which supplies water to selected Silesian agglomeration, was analyzed. The work uses laboratory tests of selected water parameters. Statistical methods were used to determine the causes of water quality deterioration.
